Subject: [PATCH 09/14] PM / devfreq: Switch to dev_pm_opp_find_freq_{ceil/floor}_indexed() APIs
Date: Wed, 12 Jul 2023 16:02:04 +0530 [thread overview]
Message-ID: <20230712103213.101770-10-manivannan.sadhasivam@linaro.org> (raw)
In-Reply-To: <20230712103213.101770-1-manivannan.sadhasivam@linaro.org>
Some devfreq consumers like UFS driver need to work with multiple clocks
through the OPP framework. For this reason, OPP framework exposes the
_indexed() APIs for finding the floor/ceil of the supplied frequency of
the indexed clock. So let's use them in the devfreq driver.
Currently, the clock index of 0 is used which works fine for multiple as
well as single clock.
